Abstract

A method for emitting a message relating to a determined type of information to be exchanged between an aircraft and a ground base reception method, and corresponding devices. The method determines a level of a securement associated with the determined type by a correspondence table, and emits the message according to a protocol having the determined level of securement.

Claims

1-15. -15. (canceled)

16. A method for emission of a message relating to a determined type of information items to be exchanged between an aircraft and a ground base, comprising:

determining a level of security associated with the determined type by a correspondence table; and

emitting the message according to a protocol having the determined level of security.

17. A method according to claim 16, wherein the correspondence table is stored in a memory in an electronic storage device.

18. A method according to claim 16, further comprising a preliminary receiving the correspondence table by communication between the aircraft and the ground base.

19. A method according to claim 16, further comprising generating the correspondence table based on a table of data that associates a desired level of security with at least one type of message.

20. A method according to claim 19, further comprising receiving a table of data by a communication between the aircraft and the ground base.

21. A method according to claim 19, wherein the generating comprises, for at least one type of message, associating a level of security with the type of message in the correspondence table as a function of the desired level of security associated with this message in the table of data and characteristics of the communication system being used.

22. A method for reception of a message relating to a determined type of information items to be exchanged between an aircraft and a ground base, comprising:

receiving the message according to a protocol having a first level of security;

determining a second level of security associated with the type determined in a correspondence table;

comparing the first level of security and the second level of security; and

accepting or rejecting the message according to a result of the comparison.

23. A device for emission of a message relating to a determined type of information to be exchanged between an aircraft and a ground base, comprising:

means for determining a level of security associated with the determined type by a correspondence table; and

means for emitting the message according to a protocol having the determined level of security.

24. A device according to claim 23, wherein the correspondence table is stored in memory in an electronic storage device.

25. A device according to claim 23, further comprising means for communicating between the aircraft and the ground base capable of receiving the table of correspondence.

26. A device according to claim 23, further comprising means for generating the correspondence table on the basis of a table of data that associates a desired level of security with at least one type of message.

27. A device according to claim 26, further comprising means for communication between the aircraft and the ground base capable of receiving the table of correspondence.

28. A device according to claim 26, wherein the means for generating comprises means for associating, for at least one type of message, a level of security with the type of message in the correspondence table as a function of the desired level of security associated with the message in the table of data and characteristics of the communication system being used.

30. An aircraft, comprising a device according to claim 23.

29. A device for reception of a message relating to a determined type of information items to be exchanged between an aircraft and a ground base, comprising:

means for receiving the message according to a protocol having a first level of security;

means for determining a second level of security associated with the determined type in a correspondence table;

means for comparing the first level of security and the second level of security; and

means, connected to the means for comparing, for deciding acceptance or rejection of the message.
